(Phys.org)—Fifty years after scientists first posed a question about protein folding, the search for answers has led to the creation of a full-fledged field of research that led to major advances in supercomputers, new ...

New research explains why so many biological networks, including the human brain (a network of neurons), exhibit a hierarchical structure, and will improve attempts to create artificial intelligence. The study, published ...

New lung "organoids"—tiny 3-D structures that mimic features of a full-sized lung—have been created from human pluripotent stem cells by researchers at Columbia University Medical Center (CUMC). The team used the organoids ...

In a study published in the journal Cell on May 24, Cold Spring Harbor Laboratory (CSHL) scientists describe the three-dimensional atomic structure of a human protein bound to a piece of RNA that "guides" the protein's ability ...
